Keyboard and Keyboard + Mice Combos with Mac (READ ONLY ARCHIVE)

[FroDawg]

Had this combo for 2 years with no problems whatsoever...until this (Monday) morning. Nothing working together although mini receiver and keyboard and mouse all seem to be working (receiver's green light comes on when inserted in working USB ports, new batteries in components). Any ideas will be appreciated. THX

I just had the same thing happen  a few days ago.  Any answers?
